Not sure what your rant is getting at but my point stands - eliminate all pollution (even naturally occurring arsenic?) and you’d reduce cancer rates by maybe 30%.
Worthwhile? Of course? Going to get rid of cancer? No.
My rant was that we're incredibly far form "doing the best we can" with out environment, 30% is an insanely high amount of things left undone that we could do. Even 10% of that, 3% is a criminal improvement not to aim for. We're unimaginably incredibly sloppy and ineffective at managing what matters most of our environment and paying insane prices for it and that's what angers me...
